LAMP.

Be it known that I, CHARLES E. GoDLEY, a citizen of the dent of Detroit, in the county of Vayne and State of Michigan, have invented a new andfImproved Lamp, of which the following' is a specification.

`This invention relates to headlight and searchlight lamps, and4 its object is to pro vide means for holding the reflector and lens ring in position so that the lamp shall be dust-proof, and which shall prevent the rattling' that commonly occurs whe.. such lamps are used on vehicles, launches and the like."

A further object of thisrinvention is to provide a locking means whereby the lens ring sha1-l be positively locked Vin position, and yet may be easily and quickly detached when desired.

This invention consists in improved posi,

'tioning and retaining means for the reflector p of a lamp; also in Y improved .means for re'- talnlng and locking the lens ring 1n position; and in such other details'as are lllustrated in the drawings and pointed. out in the claims;

In the accompanying drawings, is a side elevation of the lamp. Fig. 2 1s a longitudinal section thereof.` Fig. 3 is a perspective view Vof the l'amp-body. Fig. 4 is a perspective view et the reflector. Flg. 5 is a perspective view ofthe lens ring, showing a part of the locking means. a. detail of the means for holding the lensring in position.- Fig, 7 is adetail of the spring` for holding the reiector away from the lalnpfbody.

In the drawings, 1 indicates a lamp-body, preferably of sheet brass,

a cylinder 4 projecting from the bcad3. The flared front 2 and flange 8 together form a groove 5 within which a 'circlunferential spring() is seated. This cylinder 4 is provided with a series of pinsor projections 7 that ex- Specification of Letters Patent. Application filed september 24.1913.

The circumierential spring .6 is made of a single piece ofl wire wich is,"in general, bent into a substantial'l form. At various pointsxareormed the V-shaped loops 8,'extending upwardly inan inclined direction body of the spring, y'as-shown in Figs. 1 and 3. The endsvof the wire are joined in the manner' indicated. in Fig. 7. One end is shaped somewhat'like the letter S, and the other end is bent laterally at'9 and then passes' over the extremity of the other end, then downwardly through the first bend of the S shaped end-and upwardly through the second bend o the S. The spring 6, aftertheends 'inder 4,

The refiector 10 is nates in a cylinder upon itself lat 12 and then bent laterally to form a radial annular ange 13, having a series of notches 14, corresponding in number to the pins 7. By inserting the reflector into the cylinder 11 against .the spring 6 in such manner that the notches 14 '.will register with the inwardly extendingy ends .of the pins 7, and then turning it about its own axis, it is evident that the refiector will be retained in position in the lamp-body.

The lens -ririg is. shown substantially se1ni-.circular in cross-section, :one edge 2l being fitted resiliently over the bead 3 and the other' edge 22 being adapted to 'lit resillently against lens 23. The lens is heldl in from the `plane of the preferably parabolic in' 'cross-section, and its front portion termi- 11, which is bent back` ratenteanpr. i4, i914.
